3D printing is a mind-blowing art that allows you to create physical objects through your virtual design. Instead of using ink on paper to make the object, it uses plastic or other materials, each time adding new layers. To build up the final product. You begin by importing a digital copy of the desired make. The printer follows the blueprint encrypted in the file and prints the object layer by layer. For example, when frosting a cake that has already been baked, you want to put different plastic colors on the surface to obtain the shape you're after. The 3D printing technology offers you a wide range of objects to make, from simple toys and gadgets to components for machines and even prostheses.
